The purpose of this paper is study the effect of monetary policy on asset prices. We study the properties of a monetary model in which a real asset is valued for its rate of return and for its liquidity. We show that money is essential if and only if real assets are scarce, in the precise sense...

This dissertation consists of two essays concerning search theory. In the first essay we consider a model of directed search in which strategic sellers advertise general trading mechanisms. A mechanism determines the number of buyers that will get served and the side payments as a function of ex...

We study optimal portfolio choice in a two-country model where assets represent claims on future consumption and facilitate trade in markets with imperfect credit. Assuming that foreign assets trade at a cost, agents hold relatively more domestic assets. Consequently, agents have larger claims...

I consider a model of directed search in which strategic sellers advertise general trading mechanisms. A mechanism determines the number of buyers that will get served and the side payments as a function of ex post realized demand. After observing these advertisements buyers simultaneously visit...

I consider a model of directed search where strategic sellers advertise general trading mechanisms. A mechanism determines the number of buyers that will get served and the side payments, as a function of ex-post realized demand. Buyers observe these advertisements and visit one seller without...

We study optimal asset portfolio choice in a two-country search-theoretic model of monetary exchange. We allow assets to not only represent claims on future consumption, but to also serve as means of payment. Assuming foreign assets trade at a cost, we characterize equilibria in which different...

I study a directed search model of oligopolistic competition, extended to incorporate general capacity constraints, congestion effects, and pricing based on ex-post realized demand. I show that as long as any one of these ingredients is present, the Bertrand paradox will fail to hold. Hence, I...

In many search models of the labor market, unemployment insurance (UI) is conveniently interpreted as the value of leisure or home production and is, therefore, treated as a parameter. However, in reality, UI has to be funded through taxation that might be distortionary. In this paper, I analyze...

We revisit a traditional topic in monetary economics: the relationship between asset prices and monetary policy. We study a model in which money helps facilitate trade in decentralized markets, as in Lagos andWright (2005), and real assets are traded in an over-the-counter (OTC) market, as in...
